Hey Himanshu

Thanks for putting your question.

Mostly manager rounds are non-technical, some manager do ask technical question as well.

Never ever loose hope. for example :- you are asked a puzzle, ad you know you don’t know the answer,, show that you are trying,,

Keep on preparing for generic questions like , how will you handle a conflict with senior and what if now its junior ?
What are short/long term goals ?
What if you have to extend ?

So once you start asking these questions to yourself, you will be able to find the best answers to these.

Be confident and document some of your experiences in evernote/onenote like apps so whenever you go to interview you can remember them and use them.

Hope you have subscribed to youtube channel as well apart from email subscription to keep updated.
